Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.
Answer:
3.27 minutes
Explanation:
To solve this problem we will first convert miles/hour to km/min. For this purpose we will require following reference conversions as;
1 Mile = 1.60934 Km
And,
1 Hour = 60 min
Therefore,
As,
1 Mile = 1.60934 Km
Then,
74 Miles = X Km
Solving for X,
X = 74 miles × 1.60934 Km ÷ 1 mile
X = 119.10 Km
Therefore,
119.10 Km were travelled in = 60 min
So,
6.50 Km will be travelled in = X min
Solving for X,
X = 60 min × 6.50 Km ÷ 119.10 Km
X = 3.27 minutes
High, the enzymes in cells function or speed up reactions by lowering the activation energy.
Combustion
It is an example of a simple chemical reaction. In a combustion reaction, oxygen reacts with another substance to produce carbon dioxide gas and water vapor.
